  1. 6. A Dual-Lens Approach to Loss Given Default Estimation: Traditional Methods and Variable Analysis

    University essay from KTH/Matematik (Avd.)

    Author : William Jaeckel; Nicolai Versteegh; [2023]
    Keywords : Loss given default; estimering; jämförande studie; variabelanalys; kreditförvaltning; utlåning till små och medelstora företag; riskanalys; Loss given default; estimering; jämförande studie; variabelanalys; kreditförvaltning; utlåning till små och medelstora företag; riskanalys;

    Abstract : This report seeks to thoroughly examine different approaches to estimating Loss Given Default through a comparison of traditional estimation methods, as well as a deeper variable analysis on micro, small, and medium-sized companies using primarily regression decision trees. The comparative study concluded that estimating loss given default depends heavily on business-specific factors and data variety. READ MORE

  2. 7. Predicting user churn using temporal information : Early detection of churning users with machine learning using log-level data from a MedTech application

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Love Marcus; [2023]
    Keywords : User churn; Customer attrition; Artificial neural networks; Log-level analysis; Random forests; Decision trees; Användarbortfall; Kundbortfall; Artificiella neurala nätverk; logganalys; Slumpskogar; Beslutsträd;

    Abstract : User retention is a critical aspect of any business or service. Churn is the continuous loss of active users. A low churn rate enables companies to focus more resources on providing better services in contrast to recruiting new users. READ MORE

  3. 8. MODELING INPUT VARIABLE AGE IN SEPSIS PREDICTION USING TREE-BASED MODELS

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Oscar Wastesson; [2023]
    Keywords : Machine learning; decision trees; sepsis; classification;

    Abstract : Last observation carried forward (LOCF) is a common imputation method, regularly used for clinical data. It is based on the principle that the most recent observation that is known is carried forward to replace missing values. READ MORE

  4. 9. Explainable Machine Learning in Cardiovascular Diagnostics

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Alexander Gutell; Ludvig Skare; [2023]
    Keywords : ;

    Abstract : The major challenges in implementing machine learning models in medical applications stemfrom ethical and accountability concerns, which arise from the lack of insight and understandingof the models' inner workings and reasoning. This opaqueness has resulted in the emergenceof a new subfield of machine learning called Explainability, which aims to develop and deploymethods to gain insight into how input data is weighted and propagated through a machinelearning algorithm.

  5. 10. Increased carbon sequestration of actively restored tropical forests in Sabah, Malaysia : a comparison of natural regeneration and active restoration

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Johan Engström; [2023]
    Keywords : Degraded tropical forest; Active restoration; Carbon sequestration; Natural regeneration; Enrichment planting; Biomass accumulation;

    Abstract : As restoration with assisted natural regeneration and enrichment planting becomes a more important and popular method to restore ecosystem services and mitigate negative climate effects, these treatments and their effectiveness is heavily debated. There are three main groups of opinions regarding restoration, one is that humans actively need to help nature recover and the second is that nature itself does a better job without our help and the third is somewhere in between.
